Intelligent Transport Systems (ITS) are designed to solve various problems that current road transport systems face such as traffic accidents, congestion, and exhaust gas pollution, by sharing traffic information among people, roads, and vehicles via the latest information and communications technology (ICT). Currently, ITS technology is being developed through collaboration between industry, academia, and government to eradicate traffic accidents, eliminate congestion, and reduce CO2 emissions.

Sumitomo Electric Group is mainly engaged in the three business domains of mobility, energy, and ICT. ITS-related items are included in a fusional area of mobility and ICT, in which the group has a variety of technologies and products that support this area. The group provides total solutions from product development, design and manufacturing, software development and systems engineering to maintenance services, not only for the Japanese market but also markets overseas.

When did the Sumitomo Electric Group start offering ITS-related products?

Motorization in Japan has rapidly advanced since the 1960s, supporting economic development and improved living standards, while also seeing increased fatalities in traffic accidents and social problems such as congestion and pollution. Since the late 1960s, the Sumitomo Electric Group, in cooperation with governments, has actively worked to introduce traffic control systems, developed the world-class Tokyo Metropolitan Traffic Control Center, and contributed toward mitigating congestion and creating a safe, comfortable, and environment-friendly road traffic society.

We would like to introduce some of our ITS-related products and solutions below.

*Click the following numbers; the screen will jump to the related product guide.

(1) Traffic Control Center

The center collects and analyzes road traffic information and controls traffic signals to prevent traffic congestion and accidents as well as provides a variety of traffic information, thus centrally controlling urban traffic.

(2) Expressway Traffic Monitoring System

By measuring traveling vehicles, the system reports traffic congestion and travel time information and helps expressway management.

(3) Tunnel Monitoring System

By analyzing video images from surveillance cameras installed in tunnels, the system monitors the traffic and unusual situations (e.g. stopped, slowing, or runaway vehicles) there.

(4) Driving Safety Support System

Safe driving is supported by the provision of traffic signal, vehicle, and pedestrian information from roadside units such as optical beacons and ITS wireless radio to the on-board unit.

(5) Traffic Information Provision System

This system provides traffic information collected by the traffic control center to road users through variable message signs and optical beacons.

(6) Fast Emergency Vehicle Preemption Systems

These systems detect emergency vehicles such as police cars and ambulances via optical beacons and control traffic signals to give them higher priority.

(7) Public Transportation Priority Systems (PTPSs)

These systems detect buses or other public vehicles via optical beacons and control traffic signals to provide them with longer green lights and shorter red lights to help them comply with their route schedules.

(8) Bus Location System

By conducting wireless communications with an on-board unit in buses, the system monitors the location of traveling buses and provides arrival time information at bus stops.

(9) ITS Roadside Units

The Sumitomo Electric Group develops and produces infrastructure equipment such as roadside signal controllers and vehicle detectors.

(10) Delivery Planning System / Dynamic Management System

These systems improve efficiency in transport by designing a delivery plan that considers congestion information and monitoring vehicle locations and conditions.

(11) License Plate Reader

Utilizing roadside cameras and image processing technology, this unit detects license numbers of vehicles in real time, which data are used for travel time measurement.

(12) Telematics Terminal

This terminal provides drivers with congestion and routing information issued by the Telematics Center to assist efficient and safe driving. The Group also provides development tools for smartphone apps.

(13) New Transit System

Using induction wireless technology, this system enables conversations and emergency notifications between passengers and control centers via train radio.

(14) Telematics Center / Automatic Driving Assistance

By using vehicle information collected through mobile networks, the center issues and provides congestion and routing information to telematics terminals. This information helps driving control and hazard avoidance for automatic driving vehicles that are expected to soon become reality.

More details on these products and solutions are available on the following page.

The Sumitomo Electric Group will continue contributing toward the creation of a mobile society that is safe, secure, and comfortable even in an aging society by providing advanced ITS infrastructure and driving assistance technologies.
